Monel K500 Threaded Bars Overview
Aurum Overseas is a trusted Monel K500 Threaded Bars Supplier & Exporter, stocking high-strength precipitation-hardened fasteners made to QQ-N-286 and BS 3076 specs. Designed for extreme subsea and offshore loads, these studs combine the corrosion resistance of Monel 400 with double the tensile strength.
Our inventory of UNS N05500 Threaded Rods features a Nickel-Copper alloy enriched with Aluminum and Titanium. Thermal age-hardening gives these bars exceptional strength and immunity to sour gas (H₂S) cracking, marine biofouling, and heavy dynamic stress.
Built for subsea wellheads, marine shafts, non-magnetic drill collars, and valve stems, our Monel K500 Threaded Bars ensure leak-free performance. Contact Aurum Overseas for factory quotes, custom length cutting, and fast global shipping.

Key Advantages of Monel K500 Threaded Rods
Ultra-High Yield & Tensile Strength
Thermal age-hardening delivers a yield strength of 790 MPa (115ksi) to support extreme subsea loads without stretching.
100% Non-Magnetic Subsea Core
Maintains zero magnetic permeability even at cryogenic temperatures, preventing compass/sensor distortion in directional drilling equipment.
Sour Gas Acid & Seawater Immunity
Complies with NACE MR0175 to prevent hydrogen sulfide cracking and high-velocity marine erosion.
Cold-Sintering & Galling Prevention
Native copper-nickel matrix forms a self-lubricating surface film that stops metal-on-metal cold welding under massive assembly torque.
Quality Testing & Inspection
Aurum Overseas subjects every order to strict Quality Assurance protocols to ensure full compliance with international fastener standards and client specifications:
- Positive Material Identification (PMI): Spectro / XRF analysis confirming exact elemental composition per UNS N05500 specs.
- Dimensional & Thread Pitch Inspection: Go/No-Go gage testing and optical comparator checks ensuring exact 2A/3A and 6g thread fit tolerances.
- Mechanical Batch Testing: Tensile strength, yield strength, hardness, and elongation verification certified via EN 10204 3.1 Material Test Reports.
- Optional Specialized Inspections: Hardness testing (Rockwell C), proof load testing, or ultrasonic NDT provided upon customer request.

Frequently Asked Questions
Monel K500 contains added Aluminum and Titanium, which undergo age-hardening heat treatment to deliver more than double the mechanical strength of Monel 400 while retaining identical corrosion resistance.
Yes. Monel K500 is non-magnetic in the age-hardened condition and maintains non-magnetic behavior down to sub-zero cryogenic temperatures, making it ideal for directional drilling tools.
Yes. As a major Monel K500 Threaded Bars Exporter, we regularly deliver to offshore drilling rigs, subsea projects, and refineries across the UAE, Saudi Arabia, Qatar, Oman, Kuwait, and Bahrain.
